Vulnerability
22 Dec 2025 • Eurostar: Eurostar chatbot security flaws almost left customers exposed to possible security threats
Eurostar AI Chatbot Vulnerabilities Discovered

**Eurostar’s AI Chatbot Vulnerabilities Exposed by Security Researchers** Security researchers at **Pen Test Partners** uncovered critical flaws in **Eurostar’s AI-powered customer support chatbot**, which could have enabled malicious exploitation. The vulnerabilities included **weak message validation**, allowing attackers to manipulate older prompts to execute unauthorized actions—such as extracting system details or potentially exfiltrating data. Additional weaknesses involved **unverified conversation IDs** and an **HTML injection flaw**, which permitted JavaScript execution within the chat interface. Despite the risks, **Eurostar confirmed that no customer data was compromised**, as the chatbot lacked access to sensitive databases or login-protected information. The company stated that all vulnerabilities have since been **mitigated**, emphasizing that the chatbot operated in isolation from critical systems. The discovery highlights broader concerns around **rapid AI adoption in enterprises**, where misconfigurations and non-human identities are expanding cloud attack surfaces. While Pen Test Partners did not exploit the flaws to access user data, they warned that similar design weaknesses could pose **greater risks as chatbot functionality evolves**. The incident underscores the need for **rigorous security testing** in AI-driven tools, particularly as businesses integrate them into customer-facing operations.
